Over the summer, I picked up this 1970s vintage Orient watch from an Etsy Seller that sold me a refurbished Oris. It looks identical to the Orient Tri-Star but it doesn't have 3 stars on the dial. I've read that it is common for some Tri Star watches from the early 70s to not have three stars on the dial. No matter. I love the cool vintage look of this automatic watch, but it does have a few idiosyncrasies.
Orient Watch Movement
First idiosyncrasy: this watch is an automatic--powered by the wearers body movement. You cannot wind the watch with the crown. If you want to power it up for the day, you have to whip it around and pump it up and down about 25 times or so to get it wound up and running. I joke that it's like a vintage fitness watch. If you want it to run overnight, you have to repeat the process when you go to bed. Honestly, it's a good excuse for a watch winder. At this age, this lightly serviced vintage watch simply doesn't have much of a power reserve. The watch does seem to keep good time for a couple of days of wear.
Watch Size
My second idiosyncrasy: this watch has a 36mm diameter dial. While that is a common vintage size, it's a little small for modern wearers in western counties. The original bracelet was also a bit short for my large wrists so I replaced it with an expansion band from Walmart. The end result was excellent.
Overall
I really like this watch for its character and its mysterious origin. For about $40, it was a pretty good deal for a used mechanical watch. There are certainly better performing watches from Orient today. This one is a neat collectible novelty.
